Error configuring Virtual Machine on CentOS 6

Error polling connection 'qemu:///system': internal error Cannot find suitable emulator for x86_64 :- Virtual Machine Error CentOS.

Either your CPU doesn't support VT Technology or VT Technology is disabled in BIOS.

Type

cat /proc/cpuinfo

If you don't see the vmx flag in the output, you can't use KVM.

Hi Philix, My CPU Core 2 duo E8400 Supports VT-X & VT-D .Still problem here ...

Your CPU definately supports virtualization.
Even though the mvx flag is present, I still think there is a good chance that Virtualization is disabled in BIOS. Go through all the BIOS menus carefully, hopefully you will find something.
